Overview
A Morton's neuroma usually develops between the third and fourth toes. Less commonly, it develops between the second and third toes. Other locations are rare. It also is rare for a Morton's neuroma to develop in both feet at the same time. The condition is much more common in women than men, probably as a result of wearing high-heeled, narrow-toed shoes. This style of shoe tends to shift the bones of the feet into an abnormal position, which increases the risk that a neuroma will form. Being overweight also increases the risk of a Morton's neuroma.
Causes
Morton's neuroma seems to occur in response to irritation, pressure or injury to one of the nerves that lead to your toes. Factors that appear to contribute to Morton's neuroma include. High heels. Wearing high-heeled shoes or shoes that are tight or ill fitting can place extra pressure on your toes and the ball of your foot. Certain sports. Participating in high-impact athletic activities such as jogging or running may subject your feet to repetitive trauma. Sports that feature tight shoes, such as snow skiing or rock climbing, can put pressure on your toes. Foot deformities. People who have bunions, hammertoes, high arches or flatfeet are at higher risk of developing Morton's neuroma.
Symptoms
The most common presenting complaints include pain and dysesthesias in the forefoot and corresponding toes adjacent to the neuroma. Pain is described as sharp and burning, and it may be associated with cramping. Numbness often is observed in the toes adjacent to the neuroma and seems to occur along with episodes of pain. Pain typically is intermittent, as episodes often occur for minutes to hours at a time and have long intervals (ie, weeks to months) between a single or small group of multiple attacks. Some patients describe the sensation as "walking on a marble." Massage of the affected area offers significant relief. Narrow tight high-heeled shoes aggravate the symptoms. Night pain is reported but is rare.
Diagnosis
Morton?s neuroma can be identified during a physical exam, after pressing on the bottom of the foot. This maneuver usually reproduces the patient?s pain. MRI and ultrasound are imaging studiesthat can demonstrate the presence of the neuroma. An x-ray may also be ordered to make sure no other issues exist in the foot. A local anesthetic injection along the neuroma may temporarily abolish the pain, and help confirm the diagnosis.
Non Surgical Treatment
Treatment for Morton?s neuroma will depend on how long you've had the condition and its severity. Simple non-surgical treatments are effective for some people. Others may need surgery. If Morton's neuroma is diagnosed early, treatment will aim to reduce the pressure on the affected nerve. This is usually the nerve between the third and fourth toe bones (metatarsals). Your GP or podiatrist (foot specialist) may recommend changing the type of shoes you usually wear, shoes with a wider toe area may help ease the pressure on the nerve in your foot. Using orthotic devices, such as a support for the arch of your foot to help relieve the pressure on the nerve. Anti-inflammatory painkillers or a course of steroid injections into the affected area of your foot may help ease the pain and inflammation. Alcohol and local anaesthetic is injected into your foot using ultrasound for guidance, studies have shown that this type of treatment is effective. Resting your foot and massaging your toes may also help to relieve the pain. You can make an ice pack by freezing a small bottle of water and rolling it over the affected area.
Surgical Treatment
About one person in four will not require any surgery for Morton's neuroma and their symptoms can be controlled with footwear modification and steroid/local anaesthetic injections. Of those who choose to have surgery, about three out of four will have good results with relief of their symptoms. Recurrent or persisting (chronic) symptoms can occur after surgery. Sometimes, decompression of the nerve may have been incomplete or the nerve may just remain 'irritable'. In those who have had cutting out (resection) of the nerve (neurectomy), a recurrent or 'stump' neuroma may develop in any nerve tissue that was left behind. This can sometimes be more painful than the original condition.
